To all wiz-0m it may concern:

Be it known that l, VILLARD STRAIT SER- voss, a citizenof the United States of America, and resident of Briercrest, in the Province of Saskatchewan, Dominion of Canada, have invented certain new and 'useful Improvements in Weed Burners and Eradicators, of which the following is a specification. 4

rIhis invention relates to weed burners and eradieators, and has for its objects to destroy the wild oats and weeds of all kinds and clearing a iield of any growth which is detrimental to the raising of good crops, to so control the flame that it may be lkept in contact with the weeds long enough to perform the function desired, to provide a burner with a device to feedatornized fuel to the distributing pipe thereof, and generally to adapt the several parts to better perform the functions required of them.

The invention consists essentially of the improved construction particularly described and set forth in the following speciiication and accompanying drawings forniing part of the saine.

ln the drawings;

Figure 1 is a plan view vehicle with the thereto.

F ig. 2 is a side elevation of the same.

lig. 8 is a vertical section takenon the line 3-8 of Fig. '2.

ln the drawings, like characters of reference indicate corresponding parts in the several iignres.

Referring a vehicle of of a part of the weed burner attached to the drawings, A represents usual construction, B the weed burner comprising a, franiel@ curved upwardly to provide a shank 11 designed to be engaged by a sl eve 12 rigidly carried by a bracket 18 fastened to a platforrn 1e which. may be placed on a vehicle A of any description.

The shank 11 of 'the france is .provided with a plurality of orii'ices 15 and the sleeve has a collar perforated at 16 and provided with a pin 17 designed to engage the oriiices thus providing means of adjustanie 10 to the desired height.

orrn 14e also carries a tanlr 18 for fuel such as gasolene, kerosene or 19 is also carried by the plathas a connection 2G with the tankl and is designed to feed air into the tank 18 for a will hereinafter be described.

A gage 21 is provided on the tank 18 to measure the air pressure fed by the pump 19 and an opening 22 is provided on top of the tank whereby the fuel can be fed therein. A pipe-23 extends approximately to the bottom of the tank and is provided on its outward projection with a flexible connection 24 leading to a tube 25 extending downwardly to the heating coil 26 and to a distributing pipe 27.

The distributing pipe 27 is provided with a plurality of jets 28 and the said distributing pipe extends along and is carried by the frame l0. The tube 25v is provided with a shut-ofi' valve 29 and above this valve 'section a shut-odD valve 30 is provided to which is connected a downwardly extending tube 31 provided at its lower end with a jet 32 located in clos coil 26.

When in use theshut-o valve 29 is closed and the valve 30 opened and air-is pumped from the pump 19 to the tank 18 so that the fuel is caused by air pressure to ascend the pipe 23 and runs along the dexible conpurpose that nec-tion 24 down the tube 31 tothe jet 32v where itis lighted in order to heat the coil 26 previous to the fuel being fed into the distributing pipe 28, and in order to atoiiiiZe the fuel subsequently fed thereto.

The distributing pipe 2? is provided with a hood 33 having two walls extending downwardly and to which are connected guard rails 3d below each of the jets 28 in order -to guard the saine from tile weeds on the soil.

The jets 28 are also provided with cross wires 85 which will be heated by the burnfuel ejected from the 28 so that these cross wires may help in s dling temperature in that the tlanie wil not be extinguished.

outer end of the 10 is formed with a sleeve 85 provided with a pin 3? a caster wheel 38 having a swivel shank dit provided a pluraliti The swivel shank 39 sl' sleeve 36, the pin 3. gage the ori-.dees i0 so carried at the des-- 'ii/When using the d as shown in l eiu right or the eperator 1 JJ J 4 sition l the red il proximity `with the heating L f'. i staining the innicel - burn weedson a relatively cent to the line where it `will be and connected t0 the frame 10 by` means of the eyes 42 provided thereon.

The shut-off valve 29 is then closed, while the valve 30 is opened and the air fed from the pump feeds the fuel through the pipe 24 down to the tube 3l where it is lighted on its outlet from the jet 32 in order to heat the coil 26.. The valve 29 is then turned open and the fuel allowed to run'along the tube into the heating coil 26 where it will -be atomized,yprevious tdbein'g fed to the distributin pipe lightedand the jet as shown in Fig. 3 will have sufficient force to spread'on its-contact with the ground andbe able to large -area, adjathe jet impinges.

1 It willbe seen that great economy is ob'- tained as no flame is consumed unnecesthrough the air, but ,all comsarily, passing buston of 'fuel is carried lout at .the weed or stubble roots,'thus utilizing the igniting I carrying 'V qualities of ever particle ofthe flame ainst the materlal to be i nited. Y

The eyes 42 not engaged y the hitching arm 41 may be enga ed by the chains 43 drags 44 w ich will engage the rootsburned by the flame from the ]ets -28 and dra them, thus performing the function of arrows.

yAs many changes could be made in the above construction, and many apparently widelyrdiierent embodiments of my invention, within the scope of the claims, constructed without departing from the spiritor scope thereof', it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.,

What I claim as my invention is 1. vA. weed eradicator, in combination with a vehicle, and comprising a platform on the frame, Ua tributing pipe carried by thelframe, a p lu- 27 and to the jets 28 where.
